Pure speculation. 1) Internet, followed by 2) Ubiquitous smart phones making it to teenagers -- and/or the laptops that also seem to be ubiquitous in education, these days. A personal place to look things up, less monitored than the family or library computer. (So, the other side of the "porn epidemic"? To be clear, not attributing porn per se, but rather range of information available to those who seek it out.)
